Looks like the Motorcraft starts off very thick compared to the Quaker State, but the Quaker State has a better VI.

[URed Line]http://www.redlineoil.com/product.aspx?pid=135&pcid=21[/URed Line] - The Redline 5W-50 is just as thick as the Motorcraft at 100C, but I'm sure the HT/HS is much higher than MC. It will hold its viscosity over the OCI, whereas the MC probably won't. Use the MC or Quaker State if you won't be tracking it at any time during the OCI, but if you will be tracking it go with the Red Line. You just won't be in compliance with your warranty.

Good luck finding either the Quaker State or Red Line 5W-50. The one place that I can find Red Line locally carries the 5w30, 10W30 and 20W-50 and won't special order anything else for me. I guess there's always Amazon if you order a case at a time.

I know you said that Castrol is a no go, but their 5W-50 is right between MC and Quaker State at 100C and the VI is pretty good. It's on sale right now at AAP for $30 for 5 quarts and a Fram Ultra. You won't be able to beat that price with any of the other options available.

It's too bad that the MC data sheet doesn't quote an HTHS value. The Quaker State Ultimate Durability spec sheet quotes an HTHS of 3.98, which is significantly lower than Mobil 1 5w50's HTHS of 4.4. But the Quaker State Ultimate Durability has Ford's approval for the Boss Coyote engine, so the HTHS spec must not be very challenging. Redline's 5w50 has an HTHS of 5.9, which is out of this world compared to the "approved" oils for the Boss. Which do you think would protect the engine better? Even RL's 10w40 has an HTHS of 4.7.

So, if you do have an issue - who is going to prove you used an incorrect oil? Is a used oil analysis going to prove that?

Ford and the other OEM's have more than enough resources to determine what lubricant is in the sump.

I don't know why it is so hard for some people to swallow the concept of warranty compliance. Do we honestly think we are smarter than the OEM's here? Are we that naive that we legitimately feel that by glancing at an oil's PDS that we know more than the manufacturer and what they gleaned through extensive tear-down testing?

I spoke with the Ford engineer responsible for the Powerstroke engines. They test every aftermerket tuner, determine the failure modes and deny warranty based on their findings. ECMs store when they have had reflashes. OEMs know a lot more than we give them credit for.

And besides, they can ask for receipts.

I didn't realize the Quaker State 5w50 is now approved, which is semi-good news for my buddy with the GT500. Now, for the other side of the good news/bad news equation. Have you seen Quaker State 5w50 up here yet? I haven't looked, and usually, if I need an oddball grade, I go to Castrol, since they offer every grade one can imagine plus the kitchen sink.

 

[aquariuscsm]

Oil changes are free during the warranty period anyway,right? If so,I'd just use MC 5W50 till the warranty is up,then switch to you favorite brand.

Just speculation here, but everyone seems to agree that the engine in the GT and and the GT with Track Pack are virutually identical, yet the former recommends a 5w-20 and the latter a 5W-50. Everyone also seems to agree (and you have to guess that Ford knows this) that the MC 5W-50 shears fairly rapidly. Could it be that this engine could get by just fine on the 5W-20, but that Ford suspects the Track Pack cars will get beat on a little harder thus recommends the 50wt as extra protection for those harder use situations?

I am actually considering the purchase of a 5.0 liter Mustang prior to them going to the new body style and I think I would most likely run what they recommended until I was out of the warranty period. Even then, unless I found another oil that I thought was significantly better AND met the required specifications I would most likely stay with the OEM. Just my 2 cents.

Heck, just get some Mobil 1 15w50 or some Napa synthetic 15w50. Or, mix some Mobil 1 0w40 with the Mobil 1 15w50 and make a blend of the two.

Probably the same reason some people can't figure out oil recommendations are made for other things not necessarily for the benefit of the consumer.

id run the motorcraft and not sweat the shear. if the engine is perfectly fine to run a 5w20 it will definitely be ok running a 5w50 that shears into a low 40wt. This engine doesn't "need" a 50wt. the 50wt is spec'd on the track model for track use where the engine will spin 4-7k rpm for sustained periods of time. This will not be the case for most track packed coyote motors.

the majority of them will spend their time cruising town under low to moderate throttle. IMO 5w50 offers a large buffer zone. 5w20 offers a balance of adequate protection and highway fuel economy. the engine ECM is even designed to "limp-mode" if the 5w20 can no longer manage the heat on standard model. any thin 5w50 is still thicker than it has to be in most cases. that's my opinion.

i would run either the Quaker State or Motorcraft and be confident its being protected, even on track days.

You should of bought a 5.0L then added aftermarket components similar to the track pack. What's the power numbers between a stock 5.0L and the track pack?

No difference in power. Track pack has oil cooler and upgraded radiator.

It all has to do with oil temperature. The Coyote will go into thermal power restriction if oil temperatures get too high. I would bet that the engines that spec 5w-50 have a higher cutoff than those that spec 5w-20. Remember, viscosity isn't static, it completely depends on temperature.

Hinting at CAFE I see... And that would be relevant if we were speaking about choosing between EC oils here, but we aren't. The grade in question is 5w-50, you might as well toss CAFE right out the window, as this same oil and certification are required for the BOSS 302 and the GT500.

This isn't grandma's "drive around town" Camry, this is a car and engine that are designed to be driven to their limits and subsequently, the lubricant recommendation of the manufacturer is extremely relevant, just like with the Euro marques and their lubricant requirements.

 

[artificialist]

I would be tempted to use the new Eneos 0w50 oil here.

I'd be tempted to use an oil that will retain the manufacturer's warranty, but apparently that makes me a heretic

 

[donnyj08]

i agree OVERKILL. id run the MC or QS. with fords excellent history with modular engine durability i trust they know what lube works well in this engine and their super cars. after all the oil is blended to their specs, not anyone elses. MC oil is blended and tailored to the engines ford builds, and the specs they design. its a no brainer to me. use MC 5w50, rest easy and have fun.

Track pack GT isn't a Boss 302 or GT500. It's a GT with parts bolted on. Apparently, Ford doesn't think 5w-20 is sufficient for all driving conditions. Applying common sense, if you had a regular GT, you could also use 5w-50 if you felt it was needed. Clearly it won't harm the engine. Applying even more common sense, if 5w-20 is pretty much OK, and 5w-50 is recommended sometimes, anything in between is also likely OK. Maybe even ideal. Unless of course Ford engineers were so clever they designed an engine that could only run with oils on the far ends of the spectrum, but nothing in between. Barring sheared MC 5w-50, they figured out that too.

 

[A_Harman]

Does anybody out there know what the HTHS of the MC 5w50 is?
